One piece VS Two piece (speed)



Broad Question

How does hockey structure make a puck shoot faster?

Variables

Independent: Hockey Stick type

Dependent Variable: Speed (fps)external image images?q=tbn:ANd9GcT3xTSB-i2ROZoIOqbr275ZHON3ue6SgaV6Mpr2qU1M8akLSPIk4A


Variables That Need To Be Controlled:

same ball
same person shooting
same distance

Hypothesis

I hypothesize that the one piece will shoot faster that the two piece.

Materials List

  1. clipboard
  2. pencil
  3. copy of data table
  4. hockey puck
  5. one piece and two piece hockey sticks.
  6. meter stick
  7. digital camera.

Detailed Procedure

  1. Gather all materials and head over to Pequawket pond.
  2. Take the measurement from the internet"length of red line to goal line"
  3. Put the puck on the line and take the one piece and shoot, record data. take picture/video of every trial.
  4. Repeat steps three with the one piece ten times.
  5. Repeat steps three and four with the two piece.
  6. Impute data onto digital spreadsheet.
  7. Email photos and video to teacher.

Background Research

  • Hockey sticks are made of different materials that have there own strengths on shooting the puck. The material that is being made in the hockey stick could be wood or graphite. Some times there is both materials at once for example there could be a wooden stick but a gragiet shaft. The one piece sticks are usually graphite and the two piece stick are usually wood. they call a one piece a one piece because you can not put a shaft at the bottom. A two piece is called a two piece because you can take the shaft on the bottom out and if the bottom is broken you can replace it with a new shaft. The shafts can be wood or graphite and that's why there are combination's with wood and grafiet sticks.
  • Some sticks are made of fiber glass which is
    20%graphite 80%fiber glass
    50% graphite 50% fiber glass
    and 100% graphite.
  • Making the one piece hockey stick is a very difficult thing to do because you use extremely high temperatures that are not mixed with oxygen. Hockey sticks are made with fiberglass which has made the hockey sticks very hard to make.

Data Analysis

RESULTS


The original purpose of this experiment was to see what type of hockey stick shot faster. Each stick was tested thirty times each, so sixty times in all. I found the speed of the ball traveling by taking the time that it took, in seconds, and dividing by the distance traveled. The results of this science experiment was that the one piece hockey stick shot faster than the two piece, For example in one of the trials for the one piece it was 1.3m/p/h and the two piece was 2.4m/p/h. I know this because the results graph showed that the speed of the one piece was slightly faster than the two piece. The distance traveled was always twenty-eight feet, but the seconds varied because of how hard or soft the person shooting shot.

Conclusion

My hypothesis was that a one piece hockey stick would shoot faster than a two piece. My results did support my hypothesis. Some patterns and trends of the data was that the one piece was only slightly faster in speed than the two piece. For example, the one piece speed for trial sixteen was that the one piece had a speed of 1.3 m/p/h as the two piece had 2.4m/p/h. My test went smoothly everything was alright and I accomplished what I needed to accomplish. But, if I could improve my experiment, I would have tested different types of sticks instead of just two. An interesting future study might involve testing plants or other types of living organisms.
